Electrical Insulation
UPR is widely used as an insulating material in electrical components—switchgear, busbar supports, arc chutes, insulators, transformer parts, and motor end caps. The resin must deliver high dielectric strength, low dissipation factor, arc resistance, and flame retardancy (UL 94 V-0). SMC/BMC grades are the preferred material for compression-molded electrical parts.
Product Overview

Common Challenges
Inconsistent dielectric properties across production batches cause failed hipot testing and rework
Insufficient arc tracking resistance leads to carbonized paths and premature failure in live components
Flame retardant grades that fail UL 94 V-0 at elevated temperatures (above 130°C thermal class)
Shrinkage and flash issues in compression molding of SMC/BMC electrical housing parts
Our Solution
Aertuo supplies electrical-grade UPR tailored for SMC/BMC compression molding and wet-layup insulation applications. Key grades offer dielectric strength ≥ 14 kV/mm, arc resistance > 120 seconds, and CTI ≥ 600 V. Choose from standard electrical grades for indoor switchgear or high-CTI formulations for tropical outdoor installations where high humidity and dust conditions prevail. UL-registered formulations available on request.
